HAY RAKE AND LOADER.

SPECIFICATION forming part of Letters Patent No. 492,825, dated March 7,1893.

Application filed July 16, 1892. Serial No. 440,277. (No model.)

a T0 at whom it may concern.-

Be it known that I, HORACE MCPHERSON, a citizen of the United States ofAmerica, residing at Crete, in the county of Will and State of Illinois,have invented certain new and useful Improvements in Hay Rakes andLoaders, of which the following is a specification, reference being hadtherein to the accompanying drawings and theletters of referencethereon, forming a part of this specification, in which Figure 1. isavertical section of the machine taken on line 1 of Fig. 3 looking inthe direction of the arrow. Fig. 2 is a side elevation of the machine.Fig. 3. is a rear elevation of the machine, the rakes being omitted.Fig. 4 is a perspective view of a section of one of the rake heads, anda face view of a rake tooth, showing the manner of securing the raketeeth to the rake head. Fig. 5. is a plan of a section of one of thesprocket chains, showing a laterally extending stud for entering the endof a rake head journaled thereon. Fig. 6 is a perspective view of asection of one of the upper sprocket chain guides. Fig. 7. is a crosssection of a rake head and a side View of a rake tooth secured theretoand Fig. 8 is a perspective view of a section of another form of theupper sprocket chain guides.

This invention relates to certain improvements in a hay rake and loaderwhich improvements are fully set forth and explained in the followingspecification and claim.

Referring to the drawings A represents the two side beamsor sills of thebed frame of the machine secured together by means of the two crossbeams A. and A and supported at their forward end on the axle B of thetraveling wheels 0, and at the rear end on the caster wheel P, and saidbed frame is provided at its forward end with a tongue T by means ofwhich the machine may be attached to the rear end of a wagon upon whichit is to deliver hay.

B and B are grooved guide ways for carrying in their grooves a pair ofendless sprocket chains S, one at either side of the machine. Thesesprocket chains are each provided on their inner sides with oppositelyarranged integral studs y arranged at regular intervals from each otherthroughout the length of the sprocket chains, and upon which are pivotedthe ends of the rake heads R in the manner shown particularly in Fig. 5.These rake heads are provided with a series of spring rake teeth B. Eachrake head R is provided with a cross arm R arranged centrally on itsmachine, the guides B being located above and parallel with the guides Band are arranged at an angle with the bed sills of the machine, of aboutforty-five degrees. The lower ends of the upper guides B are secured toand supported by the posts 12. resting on the bed sills A, and theirupper ends are secured to the posts E which rest on the lower guides BE. E. are brace posts which stand on the lower guides B and support andbrace the upper ends of the posts F. The lower guides 13 have theirlower ends rest on and supported by the sills A, and their upper endsare supported by the posts E which rest at their lower ends respectivelyon the forward ends of the beams A.

a a ct a are sprocket wheels arranged at the ends of the said guidewaysfor the sprocket chains .to pass over, and said endless sprocket chainsare driven by said sprocket wheels 01..

In order to prevent rotation of the rakes and hold them to their work,and so they will not turn backward their cross arms R are arranged topass under guard bars D and C, the upper guard bar C engaging said rakearms as the rakes pass downward, and the lower guard bar D engaging saidrake arms as the rakes pass upward. The upper guard bar 0 has its lowerend secured centrally above the machine to the cross beam e secured tothe upper ends of the posts n, and at its upper end to the cross beams Cand N. The cross beam 0' connecting the upper ends of posts F, and thecross beam N connecting the upper ends of the lower guide ways B Thelower guard bar I) is similarly secured in the machine by attaching neareach end to cross bars as shown in Fig. 2. As the rakes leave the upperguard bar C their rearwardly extending ends of cross arms R areconsecutively arrested by a stirrup o for the purpose of bringing theforwardly extending ends of cross arms R under the lower guard bar D asshown in Fig. 1, by means of which guard bar D the rakes are preventedfrom turning backward as they are traveling upward with their loads ofhay. The lower ends of the guard bars 0 and D are curved upward at theirlower ends as shown at v and z to fa cilitate the passage of the rakesfrom upper guard bar 0, to under guard bar D.

G are bars or slats forming a bed upon which the hay rests and movesupward, and are supported by means of the cross bars J, E and w, thesaid cross beam w being supported by means of the depending arms Lsecured at their upper ends to the upper ends of the lower guide ways BK are side bars or slats for preventing escape of hay from the sides ofthe machine, and are secured at their lower ends to the inner sides ofthe bed beams A, and at their upper ends to the depending arms L, and attheir center to the side posts E H is a series of guard rods or barsarranged below the rake heads when they are raking hay and located sothe rake teeth pass down between them, and are for the purpose ofpreventing hay from passing above the rake heads and filling up themachine above the rakes, and assist the rakes in conducting hay to theupper end of the machine. The lower ends of said guard bars H aresecured to the under side of the cross bed. sill A", and their upperends are secured to the under side of the cross beam N as shown in Fig.1.

The axle shaft B and the shaft B pass across the machine and are boxedon bed sills A, and are geared together by means of the gear wheels Sand S so that shaft B is driven by shaft B and the traveling wheels 0boxed on axle shaft B Shaft 13 is provided on each outer end with asprocket wheel 12 shown in Figs. 1 and 2 carrying the sprocket chains Sand S which drive the endless sprocket rake chains S through the mediumof sprocket wheels a and a the said sprocket wheels being connectedrespectively by a short shaft boxed in suitable boxes on sills A, sothat sprocket wheels a may be driven by sprocket wheels a The uppersprocket chain guide B may be constructed as shown in Fig. 8 if desired.

In operation the machine is attached to the rear of a wagon by means ofthe tongue T, and as the machine is drawn along over the ground theendless sprocket chains with their rakes are driven, and the rakes carrythe hay up between the bottom slats or bars G and the guard bars H anddelivered to the wagon. The traveling wheels 0 are intended to beprovided with ordinary ratchet hubs so the machine may be turned around.By this construction and arrangement of the rakes and their guides andguards the rakes do not rotate as they are conducted in their path intheir circuit, which prevents the rakes from carrying hay down to thefoot of the machine as they return, which is the case in machines ofthis character wherein the rakes are unprovided with means forfeathering their teeth and preventing rotation of the rakes.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is as follows, to wit:

In a hay rake and loader the combination of the bed frame A. A. A postsE F, andn cross beams e E, c, and N., braces E, sprocket chain guides Band B arranged parallel with each otherand in an oblique position,sprocket chains S for traveling in said guides,'rakes comprising theparts R R R R journaled at either end on inwardly projecting studs ofsaid chains, guard bar 0 arranged to engage the cross arms R of therakes in their downward passage, guard bar D arranged to-engage saidcross arms in their upward passage, sprocket Wheels a, a, and a forcarrying said endless chains and their rakes, sprocket wheels arespectively connected with the sprocket wheels at by a shaft journaledin a box between said wheels, guide bars H for preventing material frompassing up between the rakes, side bars K, bed bars G for conductingmaterial upward to the discharge end of the machine, stirrup or arm Vfor engaging the rear ends of cross arms R of the rakes and conductingthe opposite ends of said arms under guard bar D, axle shaft B havingthe traveling wheels 0 journaled thereon and having gear wheel S securedthereon, shaft B having gear wheel S secured thereon and geared withwheel S and having sprocket wheels Q23 secured thereon, sprocket chainsS and S for connecting sprocket wheels of with sprocket wheels (i andthe caster wheel P for supporting the rear end of the machine allarranged to operate substantially as andfor the purpose set forth.
